Is there anything Mathilde could have done to make herself happy in her initial situation? Could her husband have done anything more?

Mathilde could not have done anything to make herself happy. She was obsessed with the idea that money or even the illusion of money would bring her happiness. She was unsatisfied with herself and she had to learn about who she is and what is really important in her life. Even her husband could not help her discover this. Mathilde had to explore this area for herself.
